I bought a 2005 vert with 132K miles a month ago and have been changing fluids on it over the past couple of weeks. Yesterday, I decided to do the brake fluid and used a turkey baster to inititally remove some fluid from the reservoir. I pulled out about 8 oz and refilled to max line with the same amount. I then went to start the car because I needed to reposition it in the garage. The brake pedal immediately dropped to the floor and the DSC and e-brake light (yellow) were on so I went to check the fluid level and it was down about to the middle and I refilled it again. I must have did the refill cycle a couple of more times before I decided to pour slowly and watch the level which was dropping back to the mid way point as well. I have now put in 32 oz and a 12 oz bottle and the brake fluid level remains at the same spot (middle of reservoir). There are no visible leaks anywhere and do not know where the fluid is going. I am completely baffled by this and would appreciate some guidance or help! Thanks in advance.

The reserve is also used for the clutch,maybe the slave cylinder has fallen apart.

In which case you would see something under the car...

If you are not seeing it on the floor, the only other space large enough would be the vacuum booster, which is where it goes when the seals fail.
